✍️ Sample PIC Questions & Answers
1. The moisture susceptibility of an HMA mix is most commonly evaluated using which test?
AASHTO T 283 (commonly called the Lottman test) evaluates moisture susceptibility by comparing the tensile strength of conditioned versus unconditioned specimens as the Tensile Strength Ratio (TSR).
2. Why is consistent paver speed important?
Maintaining a consistent speed ensures uniform mat thickness and compaction, improving pavement quality.
3. What is the purpose of the screed in an asphalt paver?
The screed is responsible for spreading and initial compaction of the asphalt to the required thickness and width.
4. The term 'extracted gradation' during quality control refers to:
Extracted gradation is performed on the aggregate remaining after chemically removing the asphalt binder from a plant-produced HMA sample, verifying the blend matches the JMF.
5. An inspector observes that a longitudinal joint is consistently raised 0.5 inches above the adjacent lane after compaction. This condition is most likely caused by:
Excessive overlap of the new lane over the cold joint results in a high ridge after rolling because the surplus material has insufficient space to compact flush.
6. When a paving inspector reviews plant tickets, the binder content is reported as percent by:
Asphalt binder content is reported as a percentage of the total weight of the mix (percent by total mass), not just the aggregate weight.
